在 PHP 中,我试图从图像中提取 EXIF 信息。在命令行与 mod_php 中执行相同的代码时,我得到了截然不同的结果。
在命令行中,我可以看到我需要的所有数据,但使用 mod_php 的数据很少。我想知道这与 mbstring 事情有关,但无法找出根本原因。
知道如何在 mod_php 中读取整个 Exif 数据吗?
$exif = exif_read_data($fileLoc, "EXIF", true);
foreach ($exif as $i => $value) {
if( ) {
error_log("Debug:: In $i");
foreach ($value as $j => $jvalue){
error_log(" Debug: $j => $jvalue");
}
}
else {
error_log("Debug: $i => $value");
}
}
mod_php 输出:
